Well, this would be true of a 991.2 GT3 that grenades after the expiration of its 4/50k OEM warranty period, as well.

 

Hard to have exact data, and of course the internet represents most of the negative stories.

Dundon bought an F Engine with 51k recently.

 

That was in late May. No updates?

 

Uh nice... maybe the open it and share the conditions of all the relevant parts (also bottom end / bearings).

 

I've not seen any.

Agree that should open it, and show what it looks like.

 

Isn't the 991.2 GT3's engine bullet proof? I thought they fixed the issue for the 991.2 GT3 narration.

 

The 991.2 engine is different and doesn't suffer from the finger follower issue. It's still a 9000 rpm 500 HP 4.0L... no engine is bulletproof and these things push the limits.

 

Agree but the 991.2 GT3 Engine is highly unlikely of having any issues if taken good care of in maintenance and its a very small percentage of failures.

Eventually all internal combustion engines will developed some type of issue. There is no lifetime internal combustion engine. I am afraid to post that it’s not if, it’s when.

 

The same statement can be made about the 991.1 G6 engine. It's been around for 7 years now and failures are uncommon, unlike the earlier engines which were failure prone even 1-2 years into their lifecycle. The small number that have been reported appear to be one-offs that are not repeated problems (for example, one was a random bottom end failure)

 

+ when you look at the valvetrain pictures of the recently opened G6 and a Cup engine, it looks like the G6 had less wear than the Cup at way higher mileage and lots aof track use.

 

Wootloops and I are gathering data, and will post another thread registry or so.

I can confirm from a lot of data gathering, no G6 or G0 V2 (DLC Cam G0) failures documented. We have found 1 G0 GT3 failure, and 2 G0 GT3 RS (without DLC cam) failures. Unfortunately on both GT3 RS, neither shared mileage. One was a vague story and not 100% clear if FF issue, the second was definitely a finger follower.

 

Your statement is true but not when your $150K GT3's engine blows up around 20,000 miles only.

 

The .2 is a RSR motor the one in the cup cars. The .1 was a 9A2 engine beefed up for track use but not a race derived engine, it's basically a 911 engine

 

RSR motor
Both engines (3.8, 4.0 and 4.0 2nd Gen) are based on the 9A1 block. The 1st Gen 4.0 was used in the 991 GT3 R and ran the 24h races. They changed some things with the 2nd Gen 4.0 but its not a different base engine
GT3 R engines are already different from all the street engines (camshafts, intake and some more) and the RSR ones are - still derived from the same base engine - another story again.
